Four small fixes. The be2iscsi is a potential device overrun in
consistent memory, which could have nasty consequences if the
consistent allocations are packed. The hpsa one fixes a regression
where older controllers can now get a numbering clash between the first
internal disk and the controller. The libfc one is a regression in
timespec conversions which causes a user visible issue in a command
line tool and the mpt3sas one fixes a regression where the controller
could remain permanently blocked after an ATA pass through command
followed by a reset.
The patch is available here:
git://git.kernel.org/pub/scm/linux/kernel/git/jejb/scsi.git scsi-fixes
The short changelog is:
Dan Carpenter (1):
scsi: be2iscsi: allocate enough memory in beiscsi_boot_get_sinfo()
Hannes Reinecke (1):
scsi: hpsa: use bus '3' for legacy HBA devices
Johannes Thumshirn (1):
scsi: libfc: fix seconds_since_last_reset miscalculation
Suganath Prabu S (1):
scsi: mpt3sas: Unblock device after controller reset
